Non-intrusive temperature instrumentation
September 2017, Temperature Measurement
Emerson Automation Solutions has introduced a new platform for its Rosemount X-well Technology surface sensing temperature measurement solution. The X-well with a Rosemount 3144P transmitter takes its place alongside the original WirelessHART X-well Technology to extend this non-intrusive temperature sensing solution for users in conventional wired I/O environments.
This new product expands potential application possibilities in plants and facilities where wired networks are already installed, or where WirelessHART has not yet been deployed. Other users have found X-well to be a useful replacement for difficult thermowell installations, which often have a wired connection already available.
The technology works by measuring the pipe surface temperature and ambient temperature, and combining this information with an understanding of the thermal conductivity properties of the installation and process piping to produce an accurate process temperature measurement.
A major advantage is accurate process temperature measurement without requiring any intrusions or penetrations into the process, allowing for quicker and easier installation along with simplified long-term maintenance. Users do not have to design, size or maintain thermowells. Wake frequency calculations are eliminated, as well as time spent determining material compatibility, the right insertion length and the necessary profile.
Applications that can benefit from X-well Technology include pipelines, small line sizes, high velocity flows, slurries, heavy particulate fluids, wellheads, clean-in-place processes, high viscosity fluids and harsh processes in the oil and gas, chemical, refining, food and beverage, metals and mining, pulp and paper, and other industries.
“Rosemount X-well Technology is the best of both worlds as it provides an accurate process temperature like a thermowell installation while maintaining the benefits of a non-intrusive surface measurement,” says Jason Rud, senior principal design engineer at Emerson Automation Solutions. “The original wireless version has been very successful, but our customers have asked for a traditional wired version as well. Users now have both versions now available to suit any application. Temperature measurement points can easily be added without having to shut down a process as the instruments can be installed with a standard pipe clamp procedure and ordinary hand tools, without the need for a skilled contractor.”
